Hi..
I am wondering that there is a method to calculate by a pressure gauge in the suction of the pump.(usually is fitted)
Considering that a precise gauge can give u the level.
1 ATM = 10330 mmH2O
So if u can find the specific gravity of the fluid i think you can achieve your scope....
Thank you all for your valuable posts,but i ve been realized that maybe there is a problem with control air pressure.Overpressure even 0,5 bar it can damage the diaphragm.So i am searching to that direction. For you information the valve is under guarrantee period and there is a claim to...
